Fissionable material was electrodeposited 1480900100016 over 10 titanium foils of 3 mu-m thickness. Each 1480900100017 titanium foil is sandwiched between two 2.5 mu-m 1480900100018 aluminum foils, forming the cathode. Two anodes, made 1480900100019 of the same thickness aluminum foil, are placed at 1480900100020 either side of cathode with a separation distance of 1480900100021 3 mm. Incident neutron energy was determined by time 1480900100022 of flight. 1480900100023 (SCIN) Neutrons and gamma rays emitted by the 1480900100024 fragments were measured using the Chi-Nu liquid 1480900100025 scintillator array, a hemispherical array of 54 EJ- 1480900100026 309 organic scintillator detectors. Detectors were 1480900100027 placed at a distance of 1 m from the fission chamber. 1480900100028 METHOD (TOF) Fission fragment detector was placed 21.5 m from 1480900100029 the spallation target. 1480900100030 INC-SOURCE (SPALL) Proton beam with energy of 800 MeV is 1480900100031 directed on Tungsten target producing neutrons by 1480900100032 spallation reaction 1480900100033 HISTORY (20230330C) Compiled by S.H. 1480900100034 ENDBIB 32 0 1480900100035 NOCOMMON 0 0 1480900100036 ENDSUBENT 35 0 1480900199999 SUBENT 14809002 20230330 20240626 1480900200001 BIB 3 5 1480900200002 REACTION (94-PU-239(N,F)0-G-0,PR/PAR,FY) 1480900200003 ERR-ANALYS (DATA-ERR) Uncertainties include variation across PPAC 1480900200004 foils and unfolding.
